This is a creature that I made to be an ambush predator you would hardly notice until its too late. They have hard rock shaped heads that vary in size shape and color depending on the type of rocks and color scheme of their region. They are masters of camouflage and use just about anything they can to hide and wait for prey. They also have hard natural insulating armor that is very hard to get through with fire lightning or a sword and can usually only be smashed with a hammer before they stop pursuing you. They produce a venom that makes the victim nauseous and tired. If anyone wants to help with the concept art I would greatly appreciate it. :)

If the higher-ups agree with you that there is a need for a camouflaging cave-critter, then I would be happy to lend a hand with concepts, but for now I imagine it is more unnecessary work and can't really see it happening sorry
